Rare presentation of localized gingival overgrowth with osseous defect – Case report

Abstract

Gingival overgrowth is one of the most undesirable consequences that often lead to impaired esthetics and masticatory functions, compromised oral hygiene maintenance often requiring surgical excision of the excessive tissue. Gingival overgrowth belongs to a common group of lesions designated as focal reactive overgrowths. These growths are reactive in nature. A definitive diagnosis will then enable an appropriate management strategy. Peripheral giant-cell granuloma (PGCG) is a reactive focal overgrowth, ordinarily presents as an epulis-like growth. This is of a reactive rather than neoplastic nature and its pathogenesis is uncertain. It is widely considered to originate from the cells of the periodontal ligament, occurring as a response to irritants such as dental calculus, plaque, microorganisms, dental appliances, and restorations. The purpose of this article is to report the clinical, histopathological features and treatment of a case with PGCG arising from mandibular posterior alveolus in a 34-year-old female. The overgrowth was well defined along with the bone defect, involving the buccal aspect of the mandibular gingiva. The tooth was endodontically treated, the lesion was completely excised, and the osseous defect was filled with regenerative material. The 12-month follow-up radiograph revealed successful healing with no more recurrence.
